Economic agents are aware to incur in a loss basing their decisions on their own extrapolations instead of sound statistical data, but the loss could be smaller than the one related to waiting for the dissemination of final data. A broad guidance in deciding when statistical offices should...

Philippine seasonal time series data tends to have unstable seasonal behavior, called seasonal volatility. Current Philippine seasonal adjustment methods use X-11-ARIMA, which has been shown to be poor in the presence of seasonal volatility. A modification of the Census X-11 method for seasonal...

This paper applies the programs TRAMO and SEATS to seasonal adjustment of the monthly Consumer Price Index Swiss series. It is shown how the results of the purely automatic procedure can be imporved with two simple modifications: one that emerges form the TRAMO-SEATS diagnostics, and another...

This paper evaluates similarities between a priori information supplied by the business tendency surveys (that is, expectations), and a posteriori information (that is, realizations). A priori structure is defined by fractions of respondents expressing expectations, and a posteriori structure...

This paper aims to focus on the determinants influencing the internationalization of small and medium-sized enterprises (SMEs) in Czech Republic and Russia. The objective is to investigate and evaluate the business environment and, then, examine the importance of developing and promoting...

The index of maximum and minimum level is a very useful technique, especially for decision making, which uses the Hamming distance and the adequacy coefficient in the same problem. In this paper, we suggest a generalization by using generalized and quasi-arithmetic means. As a result, we will...

Multidimensional scaling (MDS) is often used for the analysis of correlation matrices of items generated by a facet theory design. The emphasis of the analysis is on regional hypotheses on the location of the items in the MDS solution. An important regional hypothesis is the axial constraint...

We study the induced aggregation operators. The analysis begins with a revision of some basic concepts such as the induced ordered weighted averaging (IOWA) operator and the induced ordered weighted geometric (IOWG) operator. We then analyze the problem of decision making with Dempster-Shafer...

This paper uses a normative method to compare the performance of the composite leading economic indicators (CLI) after the measure was revised by the Conference Board in 1996 and 2001 with its prior design to check for a claim that the new design improves its performance in predicting a downturn...

Data mining involves extracting interesting patterns from data to create and enhance decision support systems. Whereas in the early days of data mining, some tasks already relied on statistical and operations research methods such as linear programming and forecasting, data mining methods...
